Nearly all the toll takers voluntarily wore bullet-proof vests Wednesday. Last night, bridge officials ordered everyone to put them on just in case.

"When it was first known that there was a shooting at the toll plaza of the Richmond-San Rafael Bridge we escalated at the Golden Gate Bridge and put protective wear on our toll collectors and added some law enforcement in the lanes and then once we knew there was an arrest, and then we felt like we could stand down, so this morning things were relaxed back," Golden Gate Bridge District spokesperson Mary Currie said.

The Bridge District issued the vests back in 2005, after a Golden Gate Bridge toll taker was shot and seriously wounded during a robbery that same year.

It was the only time a toll collector has been shot in the span's history.
